Application med February 6,

The object of my invention is to produce a clothes wringer structure ofthe type wheresociated with and dissociated from the lower roll by alateral swinging movement of a supplemental upper frame bar whichcarries a spring abutted upper roll and forms a finish the constructionbeing such that dissociation of the rolls, in case of accident, may beaccomplished very quickly by the exertion of a comparatively small forcetransversely in a direction either from or toward the" operator fromeither side of the wringer.

The accompanying drawings illustrate various forms of my improvedstructure.

conveniently formed of sheet metal if de-= sired, having a trough-likemiddle portion 11 within which the lower roll 12 is situated. At eachend the base is provided with an end plate 13 medially verticallyslotted at 14: to permit the shaft 15 of the lower roll to descend to aproper position. Outside of each end plate 13 is a boxing 16 open at itstop and adapted to receive a bearing block 17 for the lower shaft, theouter plate of one of said boxing's being perforated at 18 to ermit theprojection of one end of shaft 15 lower roll shaft.

Thus far the structures in the three forms shown in the drawings aresubstantially identical, differing perhaps in "minor dimensions.

Referring now to Figs. 1 to 3. Vertically removably mounted in eachboxing 16 is an anchor fitting 19 having depending legs 19 and anintermediate arc-shaped portion 20,

the legs fitting within boxing 16 and held in place inany suitable.manner suchfor instance as by readily removable screws 21. Risingvertically from the middle of the are 20 is an anchor finger 22 carryingat its upper end, on its opposite sides, anchor rollers 28 journaled onan axis parallel with the axis of the lower roll 12.

lhe upper roll25 is carried by a swinging supplemental frame comprisinga main bar 26 having depending legs 27, 27, each of which is verticallypocketed, as indicated at 28, to receive the shaft 25 to receive theupper roll bearing blocks 29, 29, which may be conveniently half blocks,and the pressure springs 30. The bearing blocks 29, pressure springs 30and upper roll shaft 25' are limited in downward movement by couplings31, 31, each of which is removby any suitable means such as screws 32.Each coupling 31 is provided with two depending plates 33, 33, separatedaxially of the upper roll by an amount slightly greater than the totalaxial dimension of the anchor elements 22-23, and each plate 33 isprovided at its lower edge with an inwardly-proof the upper roll andpermit vertical movement thereofand semi-cylindrical shown in jectin camflange 34 so arranged as to be forcib e beneath one of the rollers 23.

he swinging supplemental frame may, in the main, be conveniently formedof sheet metal and, to give a finished appearance and hide the couplingbetween the base and supplemental frame, the end elements of thesupplemental frame ma be provided with de pending 1i s 35 and e boxings16 may have arc-shape lips 36. v

a 11 order to form a definite fulcrum for the swinging supplementalframe, irrespective of the position of the upper roll in said frame,each coupling 31, on its inner face adjacent the end of the up er roll,is provided with a ange 31?, the outer diameter of which issubstantially equal to the width of slot 14. v

this construction the swinging frame is tilted to an angle of aboutforty-five degrees and the upper roll is lowered down toward the lowerroll with flanges 31' in slots 14 until the lower ends of the tilted camflanges 34 are in a position to pass under the anchor rollers 23.Thereupon the sup lemental upper. frame, fulcruming upon auges 31 inslots14, may be swung to a medial vertical position, thus forcing thecam flanges 34 under the rollers 23, thereby-forcing the upper roll downfirmly upon the lower roll and compressing the springs 30 to tent, theparts being then in the position ig. 1, in which position thesupplemental frame, being firmly anchored to the base, is in positionto'aflord a proper abutment to the springs 30 to coact with the u perroll when material is forced between the up er and lower rolls.

11 case of accident the upper roll may be immediately released from thelower roll by striking the upper bar 26 in a direction at right anglesto the roll plane and swinging it to the position shown in Fig. 3. I

In order to insure holding of the supplemental frame in its medial.position against anything but intentional displacement, the flanges 34may, at their middles, be provided with a slight depression 34 toreceive the rollers 23, these depressions not being sufiiment to add toogreatly to resistance of the anchorage to dissociation by transverseforce can applied to the upper bar 26.

Referring now to Figs. 6 to 10. As inthe form shownin Figs. 1 to 5 thesupplemental swinging frame comprises the upper bar 26, depending legs27 upper roll 25, upper roll bearing blocks 29 and springs 30,separation of the upper roll from legs 27' being normally prevented byremovable cross pins 40.

paced from the outer face of each leg 27' is a plate 41 which, near itslower edge, is jacent leg 27 by two of which laterally-spaced pins 42,42, the axes are parallel with the roll axes.

,nion pin 55 -"a slot 56 in is a vertical cam upper end with an invertedY cam slot comprising the stem portion 44, open at its upper end, andthe'connected depending arms '45, 45 adapted to receive the cam pins 42,42. he Y-shaped cam slot may, it will be readily understood, be ofvarious shapes, the construction shown .in' probably preferable forthereason that these cam slots at the middles of the branches 45 areprovided with slight depressions .45 to afford a slight anchorage'forthe pins 42 against accidental swinging displacement of the supplementalframe from its normal medial operating position.

cam slot of the form shown in Fig. 11

will be satisfactory but perhaps not quite so stable 8. structure astion shown in Figs. 7 and 8.

In this construction the parts are assem- Figs. 7 and 8 being.

the cam slot construplate 43 provided at its bled by tilting thesupplemental frame to a position in the neighborhood of ninety degreesfrom the pins 42 in the stems 44 of the Y cam slots, whereupon eachlowermost pin will move laterally into one pin may then be swungdownwardly into the other arm of the Y until the supplemental frame isbrought to a medial vertical posi-- tion, at which time the upper rollis forced the deslred exd own upon the lower roll. In the form shown inFigs. 7 and 8, when the swinging supplemental frame has been brought to.medial position, the pins 42, 42 will lie in the shallow notches 45 inthearms of the Y cam slots, thereby affording a stable anchorage for thesupplemental frame which, however, ma be readily displaced, to relievethe upper rol from ressure relationship with the lower roll, byisplacement of the upper bar of the supplemental frame to one side orthe other of itsmedial position.

Turning now to Figs. '12 to 1.4. Each boxing 16 is flanked, by anupwardly-extending anchor plate 50 provided at its upper end with aninturned flange 51 conveniently sulfiarm of the Y and the upper verticaland entering the ciently "stiffened by a down-turned edge 52,

being preferably provided a depression 53 in its under construction eachdepending swinging supplemental frame each flange medially with In thisleg 27 of the is provided ,onits outer face with a plate 54 into whichis detachably secured a trunpassed into said plate through plate 50.Each plate 54, at its upper end, is provided with a roller 57 adapted totake under the adjacent flange 51.

In this construction, when the swinging frameis swung to one side or theother as indicated in Fig. 9, there is no pressure relationship betweenthe upper'and lower rolls. Pressure relationship is established byswinging the supplemental frame to its medialvertical position,thus-bringing rollers 57 under flanges 51, the swinging frame fulcrumingupon pins 55 in slots 56.

- In the construction shown in Figs 12 to 14 the swinging supplementalframe is not normally separable from the base, as in the constructionsshown in Figs. 1 to 10 inclusive,

but separation may be readily obtained when desired, as for instance forrenewal of an upper roll, by removal of pins 55, whereupon thesupplemental frame may be readily withdrawn transversely from theposition shown in Fig. 14. Pins 55 may pass through plates 54 and intoangle pieces 60 which normally serve to limit vertical movement of theupper roll shaft bearing block.

1 It will be readily understood that any suitable supplemental drainboard construction may be associated with the trough of the base, butthis detail forms no part of my present invention and therefore is notindicated in the drawings.

It will also be understood that, in any of the forms a single bar springor leaf spring may be substituted for the coiled springs shown, withoutdeparting from my invention.
